As part of the last meeting of the Convention on International Trade of Endangered Species of Wild Fauna and Flora (CITES), held this week in Bangkok (Thailand), the national government banned fishing for oceanic whitetip shark (Carcharhinus longimanus) in Brazilian waters. The decision was made in order to preserve this endangered species.

It is estimated that up to 100 million sharks are killed by people every year, due to commercial and recreational fishing. Meanwhile, the average number of fatalities worldwide per year between 2001 and 2006 from unprovoked shark attacks is 4.3.

The Caribbean’s coral reefs have collapsed, mostly due to overfishing and climate change, according to a new report released by the International Union for Conservation of Nature (IUCN). “I’m sad to tell you it’s a dire picture,” Carl Gustaf Lundin, director of IUCN’s Global Marine and Polar Programme, said at a news briefing Friday at the World Conservation Congress in Jeju Island, South Korea.

Drawing conclusions regarding plight of sharks must be based on hard science and not drama. Sharks deserve no less.
Nature is a very complex, interwoven web of plant and animal species, ecological and environmental relationships, and an endless multitude of actions and reactions. To survive, it is constantly changing, adjusting to shifts in conditions – sometimes slowly and sometimes dramatically. Therefore, to predict the totality of change that occurs with the loss of a species is, to say the least, challenging. We like are answers neat and tidy. We are prone to look for silver bullet solutions, one size fits all remedies, and we have a tendency to view consequences in linear domino-like chains.
However, when you speak with ecological scientists, they think in terms of trophic cascade when considering man’s impact on the environment. Changes are not simple and the ultimate outcome – particularly when nature is constantly trying to adjust for the sake of survival – becomes extremely hard to predict. It can be done but it requires complex modeling and varying degrees of confidence, and is often couched in the realization that other mitigating factors can alter the outcome of a particular situation for better or worse.

Giant manta rays hit the ocean headlines today with the news that they are to gain their first ever global protection from the many problems they face.

Giant mantas (Manta birostris) are to be added to the Convention on Migratory Species (or CMS), an intergovernmental treaty set up to help get nations working together to conserve the endangered animals that roam around our planet, ignoring the political boundaries we set up.
The biggest threat to mantas is fishing. They are enormous and like to hang in predicable spots, making them an easy catch. And fishermen are increasingly targeting them to feed emerging demand from the traditional east Asian medicine trade for manta ray gill rakers – the comb-like structures inside their huge mouths that sieve tiny plankton food from the water column. (Find out more about that in an interview with Andrea “Queen of mantas” Marshall on the Naked Oceans podcast).
All nations signed up to the convention that are lucky enough to have manta rays gracing their waters, will now have to make concerted efforts to protect both mantas and their critical areas of habitat. CMS listing will also spearhead international efforts to protect these giant cousins of sharks.
Currently mantas are protected by national laws in a number of countries including Hawaii, Maldives, Philippines, and Ecuador. But being such immense swimmers, they often migrate into unprotected waters.
The CMS listing for mantas was announced at this week’s conference of parties in Norway. Sonja Fordham, president of Shark Advocates International, was there to represent a clutch of conservation groups that support the manta listing.
“We are elated that the CMS Parties have embraced Ecuador’s proposal for protecting the magnificent and exceptionally vulnerable giant manta ray” said Sonja
It was announced a few weeks ago that the giant manta has been listed by IUCN as Vulnerable to extinction.
